Cybertronians

Cybertronians are a race of sentient robotic beings that originated from the planet Cybertron.

Civil War
The Cybertronians once lived peacefully on Cybertron. However, this all ended when a civil war erupted. At the start of the war, two factions emerged: the heroic Autobots led by Optimus Prime and the tyrannical Decepticons led by Megatron. The war raged on for centuries, with casualties on both sides. The civil war had also greatly decimated Cybertron beyond repair.

At one point, the Autobots were on the verge of losing the war. Therfore, Optimus ordered Bumblebee/B-127 to establish a base on Earth and protect the planet from the Decepticons to secure the future of the Autobots. As Bumblebee fled the planet with other Autobots, Optimus stayed behind to buy them some time.

Encountering Humans
In 1987, the Cybertonians would meet humanity as the Autobots and Decepticons would soon bring their war to Earth. Bumblebee would arrive on Earth and established contact with Sector 7, a top-secret government organization that monitors extraterrestrial activity on Earth. However, Sector 7 believed Bumblebee to be hostile. Just before Bumblebee could prove his innocence, a Decepticon named Blitzwing fired on them. After a fight, Blitzwing got the upper hand and demanded Optimus' whereabouts. When Bumblebee refused, Blitzwing ripped out his vocal processors, preventing Bumblebee from speaking. Before Blitzwing could execute Bumblebee, he jabbed one of Blitzwing's missiles into his chest and then shot it, blowing Blitzwing to pieces and killing him.

Biology
Cybertronians are a robotic race, and as thus they do not breathe, consume food, or drink like biological races. Instead, Cybertronians use a rare substance called Energon as a fuel or "life force". In its raw form, it is actually harmful to them (although not to organic life) but in its processed form, it is essential to their survival. Cybertronian technology has developed to the point where they can convert most forms of energy into energon.

All Cybertronians carry a "spark" inside their bodies. As long as this spark endures and remains intact, the Cybertronian can be rebuilt, no matter how much damage the unit has sustained. If the spark is extinguished or otherwise destroyed in some way, the Cybertronian cannot be rebuilt and remains permanently dead. It is a common belief amongst the Maximals that their sparks are a part of or a fragment of Primus, the mythical creator of the Cybertronian race.

Powers

 * Stasis Lock: If badly wounded, Cybertronians can enter a protective come-like state known as "stasis lock" to preserve their life-functions & give time for their friends for effect repairs.
 * Robotic Senses: While humans have 5 senses (smell, sight, touch, hearing & taste), Transformers have 7 senses (sight, hearing, touch, smell, short-range radiowave transmission, magnetic sensitivity & electronic sensitivity).
 * Heat & Cold Immunity: Since they're composed of living metal (which is stronger & more durable than Steel, Titanium & Aluminium combined & tougher/harder than diamonds & bullets combined), Cybertronians can withstand flaming/hot temperatures up to 7,000 degrees Fahrenheit, but they cannot survive extreme heat like the sun.
